You can run a read-only MCP server that exposes live Avro data through a simple MCP interface, letting you ask questions in natural language and retrieve up-to-date results without writing SQL. This server wraps the CData JDBC Driver for Avro and makes Avro data accessible to compatible MCP clients.

How to use

Once the MCP server is running, your MCP client can discover and query live Avro data through the built-in tools. You interact by asking questions or issuing simple queries that the client translates into MCP tool calls under the hood. Typical use cases include listing available tables, inspecting columns, and running read-only SELECT-like queries to retrieve data.

How to install

Prerequisites: Java Runtime Environment (JRE) and Maven are required to build and run the MCP server. You will also need the CData JDBC Driver for Avro installed on the system where you run the server.

Step-by-step installation and run

# 1. Clone the project
git clone https://github.com/cdatasoftware/avro-mcp-server-by-cdata.git
cd avro-mcp-server-by-cdata

# 2. Build the server
mvn clean install
# This creates the JAR: CDataMCP-jar-with-dependencies.jar

# 3. Download and install the CData JDBC Driver for Avro
# Visit: https://www.cdata.com/drivers/avro/download/jdbc

# 4. License the CData JDBC Driver
# Open a terminal in the lib folder of the driver installation and run:
java -jar cdata.jdbc.avro.jar --license
# Enter your name, email, and TRIAL (or your license key).

# 5. Configure your connection to the data source (example uses Salesforce)
# Open the Connection String utility:
java -jar cdata.jdbc.avro.jar
# Configure connection string, then Test Connection. Copy the resulting string.

# 6. Create a .prp file for the JDBC connection (e.g., avro.prp)

Start the MCP server

java -jar /PATH/TO/CDataMCP-jar-with-dependencies.jar /PATH/TO/avro.prp

Note: The server Uses stdio and runs on the same machine as the client.
